Good old back and forth

I had a little bit of the good old back and forth fun with the car last week. That's to say I got the 12 volt systems wired up as well so I could jump in the car, turn the key, flip a switch and press the acceleration pedal. Not just that, but even make the car move by doing so. And move it did. Shamefully I have zero photographic or video evidence of this event, unless you count this picture which shows that the vehicle has indeed turned around.

I tried third and fourth gears which both seemed fine for taking off. No clutch required, or available, for that matter. Reverse gear was a little bit more problematic. Too much power available resulting in jerky movement unless pressing the pedal extremely gently and letting go at least as gently. Probably this jerkiness was what bent my support structure too. Oh well. At least my welds were stronger than the thick angle iron! That's worth something, I suppose. Also goes to show much power a small 8" electric motor has.

It's also quite amazing how simple my 12 volt electrics are. Especially compared to the complicated original wiring of the petrol engine. I have most of the original wire bundle ziptied in place just to get the three wires that are required for the speedometer to work. Perhaps I will remove more of the extra wiring later. All the new electric car wiring is on top of the case which houses all the high voltage wiring and the 0-5k throttle. Just a few fuses and a single relay so far.

I've also been talking to the authorities and my plans for power brakes and steering seem solid. I'll need to implement more heat that I'll ever need, but I think I'll figure that out as well. For the UNECE R100 regulation the final word is that I'll need to have my wirings checked by a certified professional and get a paper for it. That should be enough for the "MOT" check. Sounds reasonable to me.

Aux battery still needs to be secured in place.

Needs a bit of tidying up.

The mess of original wiring. Actually in use: 3 leads.
